Chapter 4

Analysis of Linear Arrays

“Array antennas are similar to cascaded electronic amplifiers in increasing gain.”

CHAPTER OBJECTIVES

This chapter discusses

  • The analysis of the arrays
  • The directional behaviour of dipoles and monopoles
  • The pattern characteristics of uniform and linear arrays
  • Pattern calculations and effects of the earth
  • Impedance matching techniques
  • Transmission loss between transmission and receiver
  • Antenna signal to noise ratio
  • Objective questions and solved problems useful for class tests, final examinations and also for competitive examinations
  • Exercise problems to develop self problem solving skills
4.1 INTRODUCTION

The gain of a single antenna element is not sufficient for most applications. Under these circumstances, ...
